Synchronisation of oestrus in groups of cycling cows and heifers. To be used in combination with prostaglandin.

Planned Breeding: By synchronising ovarian activity, PRID® enables beef cows, dairy cows, and heifers, to be inseminated at a predetermined fixed time without the need for oestrus detection. Thus, reducing the calving index and the number of cows culled.

PRID® should not normally be used prior to 35 days post-partum. It can, however, be used from 21 days post-partum for late calvers in seasonally calving herds where, in healthy cows, early service is required.
